Hand, Foot and Mouth Disease in Children: Symptoms, Contagion, and Home Care

Hand, foot and mouth disease in children is a common viral infection that often causes fever, painful mouth sores, and a rash on the hands and feet. It is usually mild and gets better on its own, but supportive care and good hygiene are important.

Overview

Hand, foot and mouth disease in children is a common viral illness, especially in babies, toddlers, and preschool-aged children. It is usually caused by enteroviruses, most often coxsackievirus. The illness is known for causing a combination of fever, painful sores in the mouth, and a rash or small blisters on the hands and feet.

Although the name sounds worrying, most cases are mild and improve within about a week to 10 days. Many children can recover at home with rest, fluids, and comfort measures. Because mouth sores can make drinking uncomfortable, careful attention to hydration is an important part of home care.

Hand, foot and mouth disease is different from foot-and-mouth disease, which affects animals. It does not come from pets or farm animals. In children, it spreads from person to person, particularly in homes, day care settings, and schools where close contact is common.

Symptoms

The symptoms of hand, foot and mouth disease often begin a few days after exposure to the virus. Early signs may look similar to many other viral infections. A child may develop a fever, feel tired, become irritable, eat less than usual, or complain of a sore throat.

Within a day or two, painful spots may appear inside the mouth. These can affect the tongue, gums, inside of the cheeks, roof of the mouth, or back of the throat. The spots may turn into small ulcers, which can make swallowing painful and lead to drooling or refusal to drink in younger children.

A skin rash usually develops on the palms of the hands and soles of the feet, but it can also appear on the buttocks, legs, arms, or around the mouth. The rash may be flat or slightly raised, and in some children it may form small blisters. Not every child has all symptoms, and some have only mild rash or mouth lesions.

• Fever
• Sore throat
• Reduced appetite
• Irritability, especially in infants
• Painful mouth sores
• Rash or blisters on hands, feet, buttocks, or legs

Causes and How It Spreads

Hand, foot and mouth disease is caused by viruses in the enterovirus group. These viruses live in the nose, throat, stool, and fluid from blisters of an infected person. A child can spread the infection even before the rash appears, and the virus may remain in stool for weeks after symptoms improve.

The illness is contagious and tends to spread easily among young children because they often share toys, touch common surfaces, and place their hands in their mouths. It can pass through coughs and sneezes, saliva, contact with stool during diaper changes, and touching contaminated objects such as cups, utensils, towels, or toys.

Outbreaks are common in child care centers and schools. Good handwashing, cleaning shared surfaces, and avoiding close contact when a child is ill can reduce transmission. If a child develops a rash that seems unusual or widespread, doctors may also consider other childhood viral rashes such as measles when making a diagnosis.

Diagnosis

Doctors usually diagnose hand, foot and mouth disease based on the child’s age, symptoms, and the characteristic appearance of mouth sores and the rash. In most cases, no special testing is needed. A careful medical history and physical examination are often enough to make the diagnosis.

The doctor may ask when the fever began, whether the child is drinking normally, and whether there has been exposure to similar illness at home, school, or day care. Because several conditions can cause mouth sores or rashes, the doctor may consider other possibilities such as herpangina, chickenpox, allergic rashes, or skin infections.

Testing may be considered in unusual, severe, or unclear cases, especially if symptoms are not typical or there are concerns about dehydration or complications. If symptoms overlap with other infections that can affect breathing or general well-being, the doctor may evaluate for related conditions such as upper respiratory tract infection.

Treatment Options and Home Care

There is no specific antibiotic treatment for hand, foot and mouth disease because it is caused by a virus. Care is mainly supportive and aims to help the child stay comfortable while the illness runs its course. Most children recover fully at home with rest, fluids, and symptom relief.

Parents can offer cool drinks, ice pops, soft foods, and foods that are easy to swallow. Spicy, salty, or acidic foods may irritate mouth sores and are often best avoided for a few days. Age-appropriate medicine recommended by a doctor can be used to reduce fever or pain. It is important for caregivers to follow professional advice and product instructions carefully.

Signs that a child is drinking enough include regular urination, tears when crying, and a moist mouth. If mouth pain is severe or swallowing is difficult, a doctor may suggest additional ways to improve comfort. When dehydration is a concern, clinical assessment and supportive pediatric care may be needed, and some children may require pediatric emergency care. In selected cases where a child is unable to maintain fluids, hospital-based intravenous therapy may be considered.

• Encourage frequent sips of water or other suitable fluids
• Offer soft, cool foods such as yogurt or puree
• Let the child rest as needed
• Keep fingernails short to reduce skin damage from scratching
• Do not give antibiotics unless a doctor has diagnosed a bacterial infection

Prevention and Reducing Contagion

Because hand, foot and mouth disease spreads easily, prevention focuses on hygiene and limiting exposure during the most contagious period. Washing hands thoroughly with soap and water is one of the most effective steps, especially after diaper changes, using the toilet, wiping a nose, or before preparing food.

Shared toys, surfaces, doorknobs, and bathroom areas should be cleaned regularly. Children should be taught, as much as their age allows, not to share cups, utensils, toothbrushes, or towels. Covering coughs and sneezes and disposing of tissues promptly also helps reduce spread.

Whether a child should stay home from school or day care depends on local guidance and the child’s symptoms. A child with fever, uncontrolled drooling from mouth pain, poor energy, or difficulty participating in normal activities usually needs to stay home. Even after the child seems better, careful hygiene remains important because the virus can continue to be shed in stool.

When to See a Doctor

Most children with hand, foot and mouth disease improve without complications, but medical advice is important when symptoms are more severe or recovery is not going as expected. Parents should contact a doctor if a child is not drinking enough, has very few wet diapers or infrequent urination, seems unusually sleepy, or has worsening pain from mouth sores.

Urgent assessment is needed if there is difficulty breathing, signs of dehydration, persistent high fever, severe headache, neck stiffness, repeated vomiting, or a child who looks very unwell. Babies, children with weakened immune systems, and children with chronic medical conditions may need closer follow-up.

If symptoms are severe, prolonged, or unclear, evaluation by pediatric specialists can help confirm the diagnosis and guide care. Acibadem International’s multidisciplinary specialists in JCI-accredited hospitals diagnose and treat childhood infections for international patients, including situations that may need pediatric care.

Frequently asked questions

Is hand, foot and mouth disease dangerous for children?

In most children, hand, foot and mouth disease is mild and clears on its own within about a week to 10 days. The main concern is dehydration if mouth sores make drinking painful. Serious complications are uncommon, but a doctor should assess any child who seems very unwell.

How long is hand, foot and mouth disease contagious?

Children are often most contagious during the first days of illness, especially when fever and active symptoms are present. However, the virus can remain in stool for several weeks after recovery. Good hand hygiene is important even after the rash and fever have gone away.

Can adults get hand, foot and mouth disease from children?

Yes, adults can catch the infection, although many have mild symptoms or none at all. Parents, caregivers, and teachers may become infected through close contact with saliva, respiratory droplets, stool, or contaminated surfaces. Handwashing and avoiding sharing utensils can help reduce the risk.

What can a child eat with hand, foot and mouth disease?

Soft, cool, and bland foods are usually easier to tolerate when mouth sores are painful. Examples include yogurt, mashed foods, smoothies, and chilled soups if they are not acidic. It is usually best to avoid spicy, salty, or citrus foods that may sting.

Does every child with hand, foot and mouth disease get a rash on the hands and feet?

No, symptoms can vary from child to child. Some children have mainly mouth sores and fever, while others develop a more typical rash on the hands, feet, or buttocks. A doctor can help confirm the diagnosis if the symptoms are not classic.

When can a child return to school or day care?

This depends on the child's overall condition and local school or public health guidance. In general, a child should stay home while fever is present, when drooling is difficult to control, or when the child is too uncomfortable to take part in normal activities. Even after returning, careful hygiene remains important.
